NurdRage Presents: 3 Cool Things of Science
We demonstrate three cool things in science including silver trees, cold-activated fluorescence and the fiery reaction of sodium chlorate and candy.
First, copper wire is placed into a silver nitrate solution. This makes trees of silver crystals grow off the copper due to a redox reaction, but by eye this is extremely hard to see. Under the microscope however you can actually see this happening in real time. And if the conditions are perfectly right, it can grow quite quickly.
Second, Dr. Soprano, a colleague of Dr. N. Butyl Lithium, donated 3mg of an interesting chemical called 9,10-dihydroplatinaanthracene-4,4'-di-tert-butyl-2,2'-bipyridine. This chemical, among other things, has the property that it is only fluorescent when solid, not when liquid. So if a non-fluorescent solution is cooled with liquid nitrogen until it freezes, it becomes fluorescent.
Third, the classic reaction of sodium chlorate and candy. Molten sodium chlorate instantly ignites flammable materials and the resulting firestorm can be quite dramatic. Normally potassium chlorate is used for this demonstration but we happened to have sodium chlorate on hand.
If you have any suggestions for experiments or demonstrations, please comment!

LIGHT
light-matches-with-acid
In this video we show Safety Matches lit with Sulfuric acid.
Concentrated sulfuric acid found in drain cleaner may be used. What's happening is the sulfuric acid reacts with potassium chlorate to produce chloric acid. Chloric acid is extremely reactive and will spontaneously set flammable materials on fire.

MAKE
make-sulfuric-acid-copper-sulfate
How to make sulfuric acid by electrolysis of copper sulfate using an inert anode. Copper sulfate is very easy to obtain in large quantities at gardening and hardware stores and provides a convenient route to sulfuric acid if the appropriate anode can be obtained.
Warning: This should be done in a well-ventilated area as hydrogen gas build up is explosive. Copper sulfate is toxic and sulfuric acid is corrosive, wear gloves when handling them.
The procedure is extremely simple, just get a copper sulfate solution, insert two electrodes and run a current through them. The anode, the positive electrode, must be an inert material that can withstand extremely oxidizing conditions. Very few materials meet this condition, platinum, lead dioxide, and carbon among them. Other metals, even stainless steel, are quickly destroyed under these conditions and cannot be used. The cathode, the negative electrode, is exposed to reducing conditions so the metal requirements are must less stringent. Copper is the best choice here since it has high electrical conductivity.
When applying power, the current should be adjusted so that corrosion at the positive terminal and bubbling at the negative terminal are both minimized. The bubbling at the negative terminal is hydrogen production and that's wasted energy that should have gone into reducing the copper sulfate.
After the solution has gone clear, filter off the particles and the clear filtrate is dilute sulfuric acid that can be boiled down to obtain concentrated sulfuric acid. It will have trace amounts of metals but for most purposes this is not an issue.

GALLI
gallium-induced-structural-failure-of-an
In this video we demonstrate the structural failure of an aluminum baseball bat induced by gallium metal.
First the aluminum metal baseball bat is filed to removed the surface layer of paint and aluminum oxide. The bat is then placed in a beaker of molten gallium and allowed to diffuse through for a couple of days. Afterward the normally strong bat is rendered extremely weak and can easily be broken with just physical strength.
What's happening is the gallium metal is diffusing in between the grain boundaries of the aluminum microcrystals and disrupts their bonding. Being unable to bond together the aluminum is rendered extremely weak. Some of the aluminum also dissolves into the gallium to form an alloy. Some people say it's an amalgam but that's a misnomer. Amalgams are mercury based alloys. Just like steels are normally iron based alloys. While some specific gallium alloys have specific names like galinstan, as a class, gallium alloys don't have a special name and they're just called alloys, they're not amalgams.

How to make phosphorescent glow in the dark powder. Also known as luminescent, photoluminescent or simply glow powder.
Warning: This experiment uses mildly toxic chemicals, wear gloves when handling them. In addition, the combustion reaction must be performed outside or in a fume-hood due to the resulting smoke and gasses.
For this experiment you'll need:

LAB N
lab-notes-back-from-vacation-and-trying
So i've been trying to make lithium in a similar way to making sodium as shown in previous videos. But lithium synthesis appears to be very slow. Fortunately, this proves that all our previous samples of sodium that was made using lithium is probably very pure since lithium cannot be made under the same conditions.
